The system is a modular one, it can receive the signals from 4-20mA transmitters locally connected to the central unit or through remote concentrators. (REM 485 modules) The central unit works as a MASTER, taking the decisions based on the input signals or just monitoring the safety integrity level and managing the user’s interface devices. Figure 1. EXcetera main unit flow chart In the main unit there are two BUS RS-485. In a SIL2 configuration both will be used to connect the in the field concentrators. OGGIONI S.a.s.

Support: [email protected] web: www.oggionisas.com Atex Certified Copyright OGGIONI sas User’s Manual EXcetera System - Rev.1.0.0 August 2013 Pag. 6/24 The EXcetera main unit can be set to operate as a MASTER, managing the remote concentrators (REM-485 modules) that, in this case, will work just as Slaves units. Alternatively the system can be set as a distributed intelligence architecture, in this case the managers of the decisions can be the in field concentrators themselves (REM 485 modules), while the EXcetera central unit obtains the information, manages the local outputs and the user’s interface units, forwarding the system general status. It is recommended to link up to a maximum of 20 REM modules for every serial line. The devices in the field can be concentrators for the link with the 4-20mA transmitters, digital I/O modules and display units. Following the main characteristics of the system: 160 transmitters 4-20mA in field (20 REM 485 modules) 120 programmable outputs 1 display modules VT Terminal in field (optional) PC interface to monitor and set the system 4 RS-485 drivers, used to link the in field devices Software Characteristics - The program code and the parameters configuration are protected from non authorized changes. The user will not have the possibility to change the software mode of operation. - The system parameters configuration is accessible only by a configuration software EXcetera_GFG, using a PC - The parameters configuration in the configuration SW is automatically verified for validity. Non valid inputs will be refused. - Only authorized personnel can change the configuration using a high level (level 2) password - The programs code update are under the manufacturer control. The download of a new software version will be possible only with Oggioni s.a.s. authorization. - The user can identify the firmware version installed on the EXcetera panel and on the REM concentrators with the LCD display and/or with the local display of the REM modules.

This is why the operation mode will reflect the requirements of the norm itself. The measuring method will be the standard one, the input signals from the detectors in the field are within the standard 4-20mA measuring range. In this range the system can identify 4 status for the different system elements: NORMAL – the device is in normal conditions, no faults and no alarms. ALARM – this is the condition to measure the system, when at least one of the alarm threshold in at least one channel has been exceeded. The event will be memorized in the event log with the details of the concerned threshold. Depending on the configuration, the output will be activated and will return automatically in the normal status when the alarm conditions will end or they will remain memorized and it will be necessary to reset them manually. If memorized, the resetting will be a Acknowledge and Reset action made by an authorized user using a password. The Reset operations are memorized in the events log, too. FAULT – One or more devices of the system are in fault conditions or they don’t work properly . The event is memorized in the events log with the details of the device in fault conditions. Depending on the configuration, the output will be activated and will return automatically in the normal status when the fault conditions will end or they will remain memorized and it will be necessary to reset them manually. If memorized, the resetting will be a Acknowledge and Reset action made by an authorized user using a password. The Reset operations are memorized in the events log, too. The fault condition will be activated in case of one of the following situations: FAULT MODES: Gas detector fault - The gas detector has an inner fault and the output signal lowers to 2mA - The microprocessor of the gas detector is in a fault condition and the Watch Dog control lowers the output signal down to 2mA - The detector is in a fault condition due to of a wrong calibration procedure.

The following situation will override the fault condition: - Alarm signals - Deactivation of a device - Test/Maintenance condition of a device SERVICE – The user, if authorized, can deliberately exclude one part of the system for maintenance, calibration, parameters configuration, etc. The Service status is used to make tests and the maintenance of the system. The test/maintenance situation can be activated for the following devices: Single input (analogue or digital) Single analogue output Single digital output Single device The operation is memorized in the event log with the details of the disengaged device.

Before starting the installation verify that the current consumption of the system devices (sensors, concentrators, actuators, etc.) doesn’t exceed the maximum capability. Alternatively it will be necessary to use an external power supply with an adequate power, in this case it is recommended to verify that the device has an appropriate EMC filter according to current guidelines.

On the motherboard there is a logic programmable matrix that controls the two serial lines on the 4 ports. The same programmable logic assures the possibility to have different configurations for the serial lines. The serial lines can be set as closed loop. In this case, the system reliability is higher, as a mechanical interruption of the loop will not switch off any device. All the devices will be accessible from both sides of the loop, through COM 1, COM 2 and likewise COM 3 and COM 4. Closed loop configuration: COM1 will be at one end of the loop and COM 2 on the other end.

In this case if the loop is interrupted from any mechanical fault, all the devices linked to that loop will be inaccessible. Normally, only two ports are used, one for every communication line. So the system is virtually divided in two main areas A and B and COM 1 and COM 2 are respectively assigned to the areas. In case of open loop: Having four connectors the user can use two connectors for every loop, having the possibility to divide the number of the devices on every single loop and go in different directions, as in the drawing.

The system is divided in 4 virtual areas and the two serial lines cover respectively two areas each: in the example COM 1 covers areas A and B and COM 2 covers areas C and D. OGGIONI S.a.s.
